BROOM.

SPECIFICATION formingpart of Letters Patent No. 668,631, dated February 26, 1901.

Application filed June 9, 1900.

fo (LZ/ whom it may concern,.-

Be it known that I, SAMUEL J. EDMIsToN, a citizen of the United States, residing at Greenwich, in the county of Washington and State of New York,ha ve invented certain new and useful Improvements in Brooms,of which the following is a specification.

Ihave produced novel and advantageous means whereby corn-straws are firmly secured in a case or head which also has provision for d detachably securing and bracing a screw-handle and 'forming a reservoir for a disinfecting fluid, and the particular improvements will be pointed out in the claims.

The accompanying drawings illustrate my improvement, in which- Figure 1 shows the broom case or head and the slots in the opposite walls of its open end for the reception of .the corn-fastening keys. Fig. 2 is a section taken in the line of the width of the case and showing the conical screwsocket for the handle, in which the screw for the handle is shown as formed upon the end of the socket and not upon the collar of the case, as in Fig. l. Fig. 3 is a Vsection taken through the handle and showing the cornstems as compressed in the keyed part of the case and the screw conical socket for the handle. Fig. 4 shows inside view the case and the corn keyed therein. Fig. 5 shows one of the double-ended keys, and Fig. 6 shows a crumb-brush with the fine corn secured to a handled case by my improvement.

For brooms the case or head 5 is of sheet metal shaped like the bound part -ofan ordinary broom,having an opening at its rounded handled end, at which a sheet-metal screwformed collar l, Fig. 1,is suitably secured,and formed with a tubular conical socket 2 to form a brace for the handle, or, as seen in Fig. 2, the handle-securing screw may be formed on the end of the conical socket and soldered t0 the inner wall of the collar, which need not in suchcase be screw-threaded. In the opposite walls the open end of the case has coincident slots 3 standing in the line of the corn-straws and preferably from aboutaninch to three inches apart. The keys 4 are doubleheaded and when inserted in the slots are turned or twisted half-way to bring their heads across the slots to engage the outer walls of the case, and thus secure the corn Serial No. 19,731. (No model.)

therein. For this purpose I make the keys Vflat and the body between the heads having a width to allow them to turn in the slots, as seen in Figs. 4 and 5. This form of the body of the key gives ita width between its heads so that in turning the key it will act as a double wedge, spreading the corn slightly y both ways or toward each end of the case, and thereby give a more complete and solid holding of the corn at the open end of the case. In Fig. 2 this result of the turning of the keys is seen, in which the opposite edges of each key are caused by the act of turning it when driven through the slots, to press the corn slightly toward the edges of the next key. I prefer to reinforce the edges of the case-head by doubling them within the case and While thus doubling the edge give greater stiifness to it and prevent any buckling effect along the edges in applying the keys. This construction also prevents the cutting and breaking of the corn-stems at the edges of the case. The slots for the keys extend through the reinforcing edge.

The handle is formed with a screw-thread and may be screwed into the screw-collar l or into the screw-formed end of the handlesocket and is therebyA rendered convenient for removal or for renewing when broken.

The brooms are made of the iinest ends of the corn, and in using a metal case it is important that it be bound in the case, so thatit will be uniformly firmly held at its open end to give Ythe projecting body the proper support. This firm support is given by compressing the open end of the case after the broom-corn has been inserted in it, so that its sides are forced together about one-third the thickness of its interior space, as in Fig. 3.v The keys are then inserted and turned to lock them in place,and the corn broom in its expansion will tend to and maintain the keys tight; but the pressing of the corn itself on and around the edges of the keys will effectually prevent the turning of the keys in the use of the broom.

The broom-corn or brush having been prop-- IOO this end is saturated with a suitable cement, leaving the keyed part loose, the dotted line in Fig. 2 indicating the extent of such eementing.

For brooms the handle end of the case is hollow around the conical handle-socket and above the cemented end of the corn to receive water or a fluid disinfectant, which will pass out into and through the corn in using the broom, as there will be sufcient leakage at the sides of the case for this purpose.

The broom can be made without skilled labor and the trimmings of the corn used for small toilet and crumb brushes in which the corn-straws are keyed within acase, as I have described and shown in Fig. 6, in which the case is formed with an open side which forms the ljaws, between which the broom-straw is keyed by a construction and in a manner precisely as described in Figs. 2 and S-that is, the case has slots in which doubleended keys are engaged to bind and secure the broomcorn within the case. In Fig. 6 it will be understood that the open sides of the case or head have slots standing in line with the straw and that the double-ended keys are inserted in the slots through the body of the corn to clamp and bind the open sides of the case upon the corn.

The case can be stamped out and the broom economically produced and the keys readily inserted by a special tool adapted to open the corn.

As a means whereby the case-chamber may be filled with a fluid the conical brace-socket. is provided with perforations in its walls, and the chamber is filled by removing the handle, and being driven into the cemented head of the corn-broom the socket is thereby braced atits inner end, so that it givesafirm support to the handle.

In Fig. l the case is shown before its open end is compressed. The collar may be formed as an extension of the case and the tubular conical socket formed with the screw for the handle and soldered to the collar.

For brooms the screw-threaded handle l0 is of wood; but for brushes the handle 10/ is formed tubular integral with and as an eX- tension of the case 5', in which the straw is secured.

I claiml. In a broom or brush, a metal case or head open to receive the straw having slots in the opposite open walls standing in line with the broom corn, in combination with doubleheaded keys whereby to engage the open walls to bind the broom-corn in the case.

2. In a broom and in combination with a case or head and means whereby the broomcorn is bound within the case at its lower open edge,ofa conical tubularscrew-socket secured to and projecting both externally and internally from and within the case and a handle having a screw-threaded tapering end.

3. In a broom a case or head for containing the corn having its ope'n end contracted or flattened upon the corn to form a binding end therefor, and a handle-receivingscrew-socket terminating in a tubular conical socketbrace, in combination with means for clamping the contracted case sides.

4. In a broom, a case or head for containing the corn having its open end flattened upon the corn to compress and form a contracted binding end therefor and a handle-receiving screw-socket terminating in a tubular conical socket-brace having perforations in its walls, in combination with means for clamping the contracted case sides.

In testimony whereof I aix my signature in presence of two witnesses.
